If you check out the Asterix albums, it is hard to find a clear map that indicates the location of the village of Asterix and Obelix. But in the album "Asterix and the banquet", there is an indication of the tour they do to collect the ingredients for that banquet. And that map (see picture) allows us to get a reasonable guess of the village. Based on my interpretation of that map, the village was close to this spot.
